Nice setup and welcome back!! Yes I, along with many others, enjoy tinkering with old Amigas. I also have a 4000 with Cybervision 64/3D and the scandoubler module. Those are hard to find. I got mine on ebay a few years ago for around $200 for the whole card and doubler. You may have to go that route if you cannot get just the doubler. That way you can use 1 monitor. Make sure the battery has been replaced as they leak and destroy the motherboard.
